Abstract
A method of forming a stack is presented. According to some embodiments, a stack can be formed by determining stack ports in a group of units and converting the stack ports. In some embodiments, the stack ports can be converted to stacking mode.
Claims17
A method of forming a stack from a group of units, comprising:
- exchanging a plurality of configured hostnames through a corresponding plurality of frontend ports associated with the group of units;
- automatically detecting a plurality of stack ports among the plurality of frontend ports based on the plurality of exchanged configured hostnames, wherein automatically detecting the plurality of stack ports includes, at each unit, if a first hostname received at a port of the unit matches a second hostname of the unit, setting the port as a stack port;
- initiating a stacking algorithm in the group of units to form the stack from the group of units;
- and
- operating the stack as a single network unit.

A stack comprising a group of units linked through stack ports and operating as a single unit, wherein the stack is formed by:
- setting a shared hostname for the group of units;
- automatically detecting stack ports in the group of units based on the shared hostname, wherein automatically detecting the stack ports in the group of units includes exchanging hostnames amongst the group of units, and at each unit, if a hostname received at a port of the unit matches the shared hostname, setting the port as a stack port;
- converting the stack ports;
- and
- initiating a stacking algorithm in the group of units to form the stack from the group of units.
2 more elements
A method of forming a stack from a group of units, comprising:
- automatically detecting stack ports based on a shared hostname by providing the shared hostname to the group of units, rebooting the group of units, exchanging hostnames between the group of units, and assigning ports that receive a hostname identical to the shared hostname as stack ports;
- forming a stack from the group of units by converting the stack ports;
- and
- operating the stack as a single unit.
